Title
(DE) Verfahren zur Herstellung eines Prüfkörpers
Abstract
(DE)

Die Erfindung betrifft ein Verfahren zur Herstellung eines Prüfkörpers (30) für eine mechanisch-zerstörende Prüfung einer stoffschlüssigen Fügeverbindung, wobei das Verfahren die folgenden Schritte umfasst: - Bereitstellen eines flächigen Faserverbundsubstrates, das aus einem Faserverbundwerkstoff aufweisend ein Fasermaterial und das Fasermaterial einbettendes Matrixmaterial gebildet ist, - Applizieren mindestens eines Prüfgewebes und eines Klebstoffes auf eine Substratoberfläche des flächigen Faserverbundsubstrates, und - Aushärten des Klebstoffes, so dass eine stoffschlüssige Fügeverbindung zwischen dem Prüfgewebe und der Substratoberfläche durch den ausgehärteten Klebstoff entsteht, wobei als Prüfgewebe ein Tressengewebe bereitgestellt wird. embedded image
